In accordance with EASA AMC48 AWO 316, section “1.2 inadvertent go-around Selection”, an inadvertent selection of go-around mode after touchdown should have no adverse effect on the ability of the aircraft to safety rollout and stop. As a result of this EASA design requirement, the TOGA switches are automatically disengaged after touchdown to prevent inadvertent selection of go- around mode after landing.
